Watchface crashes when change settings over Connect IQ

My watchface VFD crashes when change settings over aplicacation Connect IQ.

When change settings over Connect or Garmin Expess is all right. In Connect IQ simulator is also ok.

SET files are different if the settings are made from Connect and Connect IQ and have a different size!!!

Log contents:

Appname: VFD
Message: 'UnexpectedTypeException: Expected Number/Float/Boolean/Long/Double, given null'

  • With Connect Mobile the settings are downloaded (the settings file is generated server-side), and with Connect IQ it is generated by the app itself, thus no round-trip to the app store.
